Going an esthetic salon?

My birthday is coming arond, and I don't know why but I got a discout ticket for an esthetic treatments. I have never tried this kind of treatments.

I was surprised because there are many corses. Facial treatments, treatments for hips, thigh, waist, hair removal...

I always think that real excercises are better than such kind of treatments, but now I'm wondering it's not bad to try it one time.
